Help?

I'm at a loss what to do. I'm 34w2d and my daughters father left me this past Tuesday. I've been so upset I can't even bring myself to go home. I've been staying at friends houses. I have to go back today to pay my rent and I have work. But idk how to cope. The very idea of being there alone after all the time we spent there together is killing me. The idea of sleeping in our bed without being able to roll over and cuddle with him....idk what to do. He left without any warning while I was at work and I'm just a mess. Any advice is welcome, but saying just forget about him doesn't exactly work. We have been on and off for over a year, its a lil hard to just toss him out of my mind. Especially with the birth of daughter getting closer and closer.
